3 m/s2

A car starts from rest and attains a speed of 12 m/s is 4 seconds. What is the acceleration?

decelaration

Slowing down also called negative acceleration

Acceleration

The rate at which velocity changes

What symbols represent ?

a = acceleration ( m/s^2) vf = final velocity ( m/s) vi = starting velocity ( m/s) t = time (s)

Acceleration formula symbols

a= (vf-vi) / t

speed

describes how quickly an object moves, calculated by dividing the distance traveled by the time it takes.

units for speed

m/s

units for acceleration

m/s/s or m/s^2

units for distance

metres

units for time

seconds

the X axis

time is plotted
